摘要： In various example embodiments, an electronic device includes a communication module comprising communication circuitry, a memory, and a processor. The communication module is configured to receive access point (AP) information from each of a plurality of AP devices. The processor is configured to receive, from the AP information, a strength value of a signal and a unique value of the AP device that transmits the signal, and to processes the AP information, based on the strength value of the signal and the unique value of the AP device. Also, the processor is configured to create an AP list as information for indicating a location of the electronic device, based on a result of processing the AP information, and to store the created AP list in the memory. The processor is configured to determine whether the AP information satisfies a condition for performing a predefined function with regard to the AP list stored in the memory, and to perform the predefined function if the condition is satisfied.
